Plate & Shell Heat Exchanger Servicing
- Chemical Cleaning
Vahterus PSHE can be cleaned with different chemical solutions depending on the process application. These chemicals contain additives that makes cleaning more effective as they dissolve scaling and particles. Example chemicals are: Nitric acid, phosphoric acid, Sodium Hydroxide and more.
Typical fouling of PSHE are usually loose particles that accumulated at the surface of the plates. These particles or fouling can be easily remove with backflushing of water or warm water with higher velocity.
- Mechanical Cleaning
Lastly, mechanical cleaning can be done if all else fails by directly removing the plate bundle from the shell and spray the plates with high pressure water jet.
